Summary of "Nano adamantane-conjugated BODIPY for lipase affinity and light driven antibacterial."

The increasing number of resistant bacterial strains has raised efforts in developing alternative treatment strategies. Lipase is highly expressed in most bacteria and lipase targeting dyes will be non-sacrificed materials for a sustainable method against microorganism. The combination of chemotherapy and antimicrobial photodynamic inactivation (aPDI) method will be an effective method due to enhanced antibacterial activity. Here we reported the spectroscopic features of five boron dipyrrolylmethene (BODIPY) derivatives with different functional groups for lipase affinity and antibacterial activity. Lipase affinity tests and antibacterial assays were conducted by spectroscopic methods. Adamantane-conjugated BODIPY (BDP-2) was found to be the active compound against E. coli. Next, BDP-2 was brominated, and then assembled with PEG resulting biocompatible BDP2-Br@mPEG nanoparticles. The MTT assay indicated that BDP2-Br@mPEG was less toxicity on BGC-823 cancer cells without irradiation. The BDP2-Br@mPEG can inhibit the proliferation of E. coli and damage the membrane of bacterial cell under green LED light irradiation. The results proved BDP2-Br@mPEG can be a very promising green LED light driven antibacterial material.

Medical and Biotech [MESH] Definitions

Compounds that increase the enzymatic activity of LIPOPROTEIN LIPASE. Lipoprotein lipase activators have a potential role in the treatment of OBESITY by increasing LIPID METABOLISM. Note that substances that increase the synthesis of lipoprotein lipase are not included here.

An inherited condition due to a deficiency of either LIPOPROTEIN LIPASE or APOLIPOPROTEIN C-II (a lipase-activating protein). The lack of lipase activities results in inability to remove CHYLOMICRONS and TRIGLYCERIDES from the blood which has a creamy top layer after standing.

Light driven chloride ion pumps that are ubiquitously found in halophilic archaea (HALOBACTERIALES).

Photosensitive protein complexes of varied light absorption properties which are expressed in the PHOTORECEPTOR CELLS. They are OPSINS conjugated with VITAMIN A-based chromophores. Chromophores capture photons of light, leading to the activation of opsins and a biochemical cascade that ultimately excites the photoreceptor cells.

A tricyclo bridged hydrocarbon.
